As the use of social media becomes more common, it is often claimed that a media environment arises in which traditional distinctions between concepts like online and offline, producer and audience, citizen and journalist become blurred. This studys purpose is to identify and explore the implications for contemporary news stories. Using a content analysis of Belgian election campaign coverage in 2014, we study the role of five newspapers, two daily television newscasts, seven current affairs programmes, radio news bulletins, three news websites, and a selection of Twitter accounts in creating and shaping news stories. We find that the analytical distinction between platforms still matters, since they have different roles in creating and shaping news stories, suggesting that different platform-specific logics are at play. Twitter is an important factor in launching and shaping news stories, but it tends to be dominated by establishment actors (journalists and politicians), whereas citizens only play a modest role.
